2.   KFT for A ................................................................................................Default 10000 
 
 
   
In order to make the EMO 500 display the correct Totalized Value in Engineering 
Units, again the most important thing to know is the K-factor of the flow meter.  The 
K-factor is the relationship between the amount of the impulses and the engineering units. 
                
 
 
 
     
In order to calculate the KFT for the EMO 500 apply the following formula.
 
 
                                     10000 
                     KFT =                                  
   K-factor
 
 
   
The KFT is the number that should be entered in the Globals Programming section.  The 
K-factor is the number published by the manufacturer as the average K-factor of the flow 
meter.  If this is published in imp/Gal the totalizer can still be set in, say cc's , by 
converting the K-factor to imp/cc.  10000 is a constant
           
           For example: A flow meter has a K-factor of 106666.0 imp/Gal and the display 
should show gallons/minute. 
 
                                  10000 
                     KFT=    
 
 = .9376 Gal 
                                 10666.0                     
 
                       
        
The number 9376 would be entered as the KFT and then the DP (decimal point) key 
would move the DP to 0.937. (See note below). 
 
     
NOTE: We recommend removing the insignificant decimal numbers often produced 
by calculator mathematics. These are mathematically redundant and offer a misleading 
level of precision in the display.  We recommend using a maximum of 4 digits regardless 
of the decimal point.
 
                      
              Example:     
for 60.675,  enter 60.6 
                         
 
for  2.34543 enter  2.345
 
 
NOTE:  
The largest number that can be entered as a KFT is 65000. Refer to KFR note 
above.
